HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 470, 784 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 470, 784 is 2 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 470, 784 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 470, 784 is 2.
HCF(470, 784) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 470, 784 is 2.
Step 1: Since 784 > 470, we apply the division lemma to 784 and 470, to get
784 = 470 x 1 + 314
Step 2: Since the reminder 470 ≠ 0, we apply division lemma to 314 and 470, to get
470 = 314 x 1 + 156
Step 3: We consider the new divisor 314 and the new remainder 156, and apply the division lemma to get
314 = 156 x 2 + 2
We consider the new divisor 156 and the new remainder 2, and apply the division lemma to get
156 = 2 x 78 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 470 and 784 is 2
Notice that 2 = HCF(156,2) = HCF(314,156) = HCF(470,314) = HCF(784,470) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 470, 784?
Answer: HCF of 470, 784 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 470, 784 using Euclid's Algorithm?
Answer: For arbitrary numbers 470, 784 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
